  氨基酸衍生的离子液晶

  摘要：

  合成了新型的手性氨基酸衍生的离子型液晶，其胺和酰胺部分作为咪唑鎓头基和烷基链之间的间隔基。合成中的关键步骤利用了相对罕见的SO 3微波辅助反应中的离去基团。介晶的介晶性质是通过差示扫描量热法（DSC），偏振光学显微镜（POM）和X射线衍射确定的。所有液晶盐均表现出具有强相互指状的双层结构的近晶A中间相几何形状。立体生成中心的空间体积的增加阻碍了中间相的形成。在苯丙氨酸衍生的衍生物的情况下，与其他氨基酸衍生物相比，烷基链较短的同构行为被观察到，表明苯基部分具有额外的稳定作用。

  Gelator backbone conformational flexibility plays an important role in a supramolecular self-assembly which is synergistically assisted by solvophobic interaction leading to a gelation of three sets of hydrophobically modulated dipeptidic gelators.

  Self-healable, multi-stimuli responsive metallo-hydrogels based on a series of tyrosine containing amphiphiles have been discovered. Formation of these metallo-gels is highly selective to Ni²⁺ ions. Moreover, the self-healing property can be modulated by varying the chain length of the corresponding gelator amphiphiles.

  1-beta-D-Arabinofuranosylcytosine (Ara-C, Cytarabine) is one of the drugs used for acute nonlympbocytic leukemia (ANLL). However, the bioavailability of Ara-C is relatively low due to its low lipophilicity. In order to improve the lipophilicity and bioavailability of Ara-C, a series of N-4 derivatives of Ara-C, i.e., (fatty acid)-(amino acid)-Ara-C analogues, were prepared. The 15 derivatives synthesized were characterized by their melting points, optical rotations and partition coefficients. It was found that the Ara-C derivatives synthesized in this study were more lipophilic than Ara-C as determined by their partition coefficients. Their in vitro cytotoxicity and in vivo anti-tumor activity were determined and compared with that of Ara-C. It was found that the derivatives were more active than Ara-C in Hela cells, but not in HL-60 cells. The in vivo results showed that some of the derivatives were more effective than Ara-C in mice bearing S-180 tumor while others showed a decreased activity in comparison with Ara-C.
